Rails 3.1 textile/RedCloth for static pages?

People,

I have used textile markup for static pages in the past - it seems I
didn't need to use the Acts as Textiled plugin - but only had to "gem
install RedCloth" and rename view .erb files to have a ".red"
extension. However I have just started experimenting with Rails 3.1
and haven't been able to get textile markup static pages to work (I
have installed the gem).

Could someone tell me what steps are necessary?

Thanks,

Phil.
